I really want to drop a jdm h22a1 into my 91 accord, but i am curious if there are any drawbacks. I am looking into getting one with the jdm 5-speed lsd tranny with the jdm ecu. Anybody do this or know about any problems I may run into? Any info will help...Thanx.

Now I'm not trying to be a dick, and I usually don't tell people to search. But seriously, it's been covered before. (big red letters at top right of page.)

agreed. you gotta search. most topics you can think of may have been covered. but anything can have its drawbacks if not done correctly. the 4th gen is a direct drop in though unless your going from auto to manual. but even that is direct but depends on the route you take with the tranny.

Even if you're a noob you can still search...anyway like was said there can be drawbacks to anything. I have a 92 accord with an h22 in it and I love it. The one drawback I found was that I learned that the h22 is not the best motor for boost, other than that it's a very good motor to put into a 4th gen Accord.

Why did you run boost on your's? What motor is better for boost...?

For all the "search search search" you guys said you could have easily answered his question. In any case, NO, there are no drawbacks with dropping that motor in the CB chassis. If you're handy with a wrench and have another car or someone to drive you around for a week, you can probably do the swap yourself with a buddy. The motor will have less miles and with some TLC be good to you for a long time...go for it.

I usually answer questions, and don't tell people to search. However, it is unnecessary to start another H22 swap thread when it has been covered numerous times before. His question would be answered much better by searching through several archived posts to gain a multitude of information, instead of what was said in this one post.

The f22 is better for boost. Here is some reading:

^^ Thanks a lot, there were a lot of debates similar to that but I managed not to see those. Answered a lot of questions. But brought up a new one. It appears that some people insinuate that your stock manual tranny will eventually give out if you boost your f22b1?

i_kick_turtles

The f22bx trannys are the same as the f22ax trannys. They've handled over 600 whp before.

a manual can pretty much handle what ever you throw at it. its the auto that will give if they aren't beefed up. only reason why some don't think the h22 is a good motor to boost is due to lack of knowledge. arguements of the block, the ringlands, the pistons and the cams have all been made from what I have seen. with the correct approach it can be accomplished reliably. everything starts with research.

^^ Thanks a lot for the replies. I was semi worried for a second and was contemplating a H22 manual tranny.

flight50

if you want shorter gears, quicker accleration, or if your going n/a then get the h22 tranny. boosting, go for a longer gear tranny. lsd will kick *** especially matched up with the h22.

The H22 also has weird sleeves that need special pistons...I think Mahle JUST came out with a piston kit for stock H22 sleeves. They're mad thin and they need special tooling to be honed and stuff...

But beyond that I don't see why boosting an H would be a problem. 8psi would yield an assload of power, and with a good tune it would be as reliable as any F but with a lot more power. Just gotta keep it cool and say a prayer for your ringlands before you start the car up. High compression boost+ REAL VTEC FTW!!!!

Thanks for the responses to all those guys who didn't just tell me to search... I didn't realize how many threads were already on there...

Anyway, what sportyaccordy said is true... I read in the March issue of Honda Tuning Mag in the article "Bored to be Wild" that the h22 block is all aluminum, and yes it can be bored over some (0.25 mm or 0.0098 inches) without having to use aftermarket sleeves. Mahle came out with 0.25 mm overbore forged pistons called there Gold Series. This sounds like a good idea for you h22 owners who have scored cylinder walls. These must be a good product because the Porsche 911's have the same style aluminum block and they come with factory Mahle pistons... Can't wait to get my h22!
